Currently there are 10 players in the team. 40% is experienced, so total experience player is [tex](0.4)(10)=4[/tex].
After addition of "x" players in the team, the percentage of experienced player on the team would be [tex]\frac{4+x}{10+x} * 100[/tex].
A. Original ratio of experienced to total players:
There are 4 experienced player (as we figured out earlier) and total 10 players, so the original ratio would be [tex]\frac{4}{10}[/tex]
B. Final ratio of experienced to total players:
Final ratio means after adding "x" players. So experienced players would increase by "x" from 4, and total would also increase by "x" from 10. So we have [tex]\frac{x+4}{x+10}[/tex] as the final ratio
C. Final total number of players:
Initially there were 10 players and after adding "x" to them, we have [tex]x+10[/tex] players as total
ANSWER:
A. [tex]\frac{4}{10}[/tex]
B. [tex]\frac{x+4}{x+10}[/tex]
C. [tex]x+10[/tex]
